The concept is really interesting and also fits the limitation to a t, because it gets chaotic trying to understand how to actally move.
The graphics are fine and are designed well enough; They aren't pixelperfect though, and therefore break the aestethic quite a bit.
On the technical side the game isn't solid, you can easily clone too many of your characters, to the point where the game freezes. This didn't happen deliberately, it happened while normal play, so maybe you should look into that.
Overall a good idea, sadly hampered by a lack of polish :<
